To all whom it may concern:

Be it known that 1, Jon Lnwis a subject of the King of Great Britain, residing at No. 16 Bathurst Park, Lydney, Gloucestershire, England, have invented certain newand use- .ful Improvements in a Combined Tinning and Cleaning Machine, 'of which the follow-' ing is a specification. 1

My invention has referenceto machines used in the manufacture of tin plates and 1 sheets and other .metal coated plates and sheets.

I willdescribe my invention as applied to the manufacture of tin plates. In the ordinary manufacture-of tinplates the plates to be tinned are passed through a t-inning machine and afterwards through a cleaning machine, a boy (called the catcher being employed to receive. the plates as they emerge, one by one from .the grease pot of the tinning machine and to transfer them to the cleaning machine.

' Various attempts have been made from time to time to dispense with the hand labor hereinbefore referred to in transferring the plates from one machine to the other and thereby ,to combine the two, machines but the combined machines as heretofore constructed. have more or less failed to answer the requirements of the manufacture,either from defects in the transferring mechanism of the combinedmachinesor through then0n provision of ready means of" access to the grease pot of the tnmmg machine for supplying molten tm 'to. the top rolls of the grease pot and for permitting of the re moval of burnt grease, scruff .and the like which collect at the meeting surfacesof the molten tin and grease.-

My invention consists of the improvements"hereinafter described in and connected with the automatic lrransferring mechanism of combined mach-in es wherebythesaid machines are rendered very eflicient and the ob jections herett'ifore attending combined machine s are entirely obviated. I

In the accompallying drawings Figm'e 1 represents in plan so much of a coii'ibii'ied tinning and cleaning machine 'as'is necessary for the understanding of my -mvention. .F 1g. 2 is a part end elevation and part" section gof.

"the same looking in the direction of the arrow'in Fig. 1; and Rig. 3 i's a vertica section 'on the dotted line Fig. l

and 5 are vertical sections taken onthe dot- Figs'. 4

ted .li'he Y'Y Fig. l the parts being in different positions in the two'figures. Figs. 2, 3,4: and 5 are drawn to a larger scale than Fig. 1. The same letters of reference indicate the same parts in the several figures of the drawings.

a is the grease .pot' forming the rear end of the tinning machine and 7), c are the upper and lower pairs of rolls of the grease pot. d IS'tllQflOllt trough or half of the cleaning machine. i

b Over the grease pot a I arrange a frame 0 with traveling wheels f, f situated so as to .be capable of traveling on the rails 9,9.

By this a1 'angement the frame 6 and parts carried by it can be readily removed from over tie grease pot use as to facilitate access o the grease pot when required and can afterwards be as readily returned to its normal position.

The frame'e carries along or continuous roller 71, preferably covered; with felt or the like, and three (or other number) of short roller-s i also covered with felt or the like. In connection with the rollers h,z' are inclined trays or chutes 7r. Instead of short rollers 2' pairs of disk-like rollers may be employed as is indicated in dotted lines in Fig. 1. Y

To permit the backward and forward motion of the frame 6 the chutes Jr are fixed at or near their-upperends to aspindle l having on one end an arm or crank 5 by which the spindle4 can be turned so as to bring the chutes 7c Into a horizontal or approxi- -mately horizontal planejia-nd thereby permit them to short rollers 2' (or pairs of disk rollers) on I thelong or continuous roller 11.

In order to render. th supply ot molten tin to-theupper pa1rI-'of'-,-grease pot rolls 7) less frequent than is ordii'i'arily necessary .I

arrange under the said rolls 72,5 troughs v7mm Which are filled from time to time with tin so asto insure, the rotation of the rolls '6, b in'm'olten tin. Guides 12 11 conduct the I tinned'plates to the rollers Inf and inclined rods 22 cause the said plates to fall on to the chutes is. Tofacilitate the motion of the plates down the chutes la and to prevent abrasion of the plates stout copper wires 1' are fixed to the said chutes 70 so as to consti tute rails on which the plates descend to the endless traveling .band or conveyor 8.

Over the traveling band or conveyer s is a series of rods 6 terminating at the outer side of the traveling band 8 in a stop plate or bar n. By this arrangement the tinned plates descending the chutes are preserved from contact with the traveling baud .9 until clear of the chutes and the plates when clear fall on the side ofthe rods 2 in thedirection of motion of the traveling hand 8.

Although I have represented the tinning part of the combined machine as arranged for the treatment of plates passing through" the machine in a series of three parallel rows yet the tinning portion of the machine'may be constructed for-the plates to pass therethrough in more or fewer than three rows.

Atthe delivery end of the traveling band s is the inclined table or frame' 2) of the cleaning machine the said table or frame or having near its lower end the pivoted frame iron which the edge of-the plate delivered .on to the table temporarily rests until permitted to enter the cleaning machine d in the manner hereinafter described.

At one side ofthe wheel 00 of the cleaning machine-a are projections or tappets 3 which come-in contact with an arm on the shaft or spindle of the pivotedframe 10 as is illustrated in Fig. 5. The further or continued rotation of the Wheel a effects the turning of the arm 2 and pivoted frame 10 as is illustrated in Fig. at for the purpose of deliver? ing the'plate on the table or frame '0 into the trough of the cleaning machine (Z; To prevent a plate falling directly from-the traveling band 8 into the cleaning machine when the pivoted frame to is in the position Fig. 4 I combine with the, pivoted frame in and inclined table or frame 1) a stop plate or frame 1 carried by vertically guided rods I claim as new and desire to secure by. lqetters Patent is 1., In amachine for. tinning and cleaning metal plates,atl e combination with cleaning devices and agrease pot of a metal coating bath, of a f 'amemovable in opposite threw tions over. the grease pot and tally removable from the latter, movable devices carried by the frame for engaging the plates and for transferrii'ig said plates from'the metal coating bath to the cleaning devices, and means over the grease pot for movably supporting said frame, said means being in a. position to permit free access to the grease pot when the frame is withdrawn;

2.: In a machine for tinning and cleaning metal plates, the combination with cleaning devices and a grease pot of a metal coating bath, of a frame movably and removably supported OVtfl'illO grease pot, rollers carried by the said frame for receiving the plates between them and continuing the upward movement ofthe latter, and guides between the said grease pot rolls and the rollers carriedby the frame, the guides being held in the top portion of the grease pot and the frame longitudinally movable over said pot.
